.To all whom t may oon/cern:

Beit known that I, EDUARD RUBIN, of Thun, in the Republic of Switzerland, have invented certain new and useful Improvements in Ride-Bullets, of which the'following is a Axo metal;

specification.

This invention has reference to that class of A'ride-bullets in which an 'interior core of soft metal is inelosed in an exterior casing of `hard and the invention consists of ,a ,ridebullet of lead or other softmetal inclosed by a casing of harder metal, which easing is of greater thickness 'atithe `point and. bent over thebase ofthe bullet. In the accompanying drawings, Figures 1 and 2 represent, respective1y,a side view and `a vertical central sectionof my improved buleoveringshelhwhichis made of steel, iron, i copper, or other suitable hard metal.

" 3o cup'shape, after' which the cup is drawn out to the length required by let; and Figs. 7, 4, and 3 represent the different stages. tirongh which the casing or `'zo coveringshell passes in the course etmakingv the bullet.

Similar letters of reference indicate correspending` parts.

.In the drawings,A representsa ball of'lfead,

cobalt, or other soft metal; and B, a casing or The casingor coreringshell Bis made from a disk-shaped blank, a, which is drawn into side wall of the the size of the ball A, as shown in Figs. 6, 5, 4, and 3. v The thicker bottom of the shell is finally shaped so as to form thepoint of the bul- 1ct, which `is thereby of greater thickness than the side of the casing. When the casing or shell B has been drawn out toits proper 1ength,the ball A is inserted `into the saine and the shell bent over the base of the ball, `as shownv in l Fig. 5; The bullet is then pressed'into the desired shape, whereby` the ball and easing are intimately united. Any shape may be given to the ball by pressure. Owing to the If the ball be vmade of cobalt, which has a comparatively high `specific gravity, thesame is placed in pulverized form into the shell.

thickness of the bottom of the shell, the pointy retains its greater thickness, as shown in Fig. 2.

Thelatter is then bent ov r at the base and the bullet finally pressed in o proper shape in a bullet-press.

I ain aware that ride-bullets consisting of a softmetal core and an inclosiug casing of harder metal have been -inade heretofore for the purpose of avoiding the leading of the ride-grooves of the barrel that takes place by using bullets having an exterior shell of soft metal. My invention'is an improvement on this class of bullets. as by the thickening of the casing at the point a greater penetrating 6o power and vgreater steadiness in flight is ob-
